...HEAVY RAIN THREAT INCREASES THIS WEEKEND...

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...Today and Tonight.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing through early evening and again after midnight.

DISCUSSION...
Very isolated showers and thunderstorms will continue through the
rest of the afternoon across far northeast Oklahoma and into
western Arkansas. This activity will diminish with the loss of
daytime heating.

There is also a small chance that additional thunderstorms may
develop after midnight across parts of eastern Oklahoma, mainly
across parts of southeast Oklahoma, nearest a frontal boundary.

Severe weather is not anticipated with either the afternoon or the
early Saturday morning storms.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
SATURDAY AND SUNDAY...Thunderstorm Potential...Heavy Rain Potential.
MONDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
TUESDAY...Thunderstorm Potential.
WEDNESDAY AND THURSDAY...Thunderstorm Potential...Dangerous Heat Potential.

EXTENDED DISCUSSION...
A complex of thunderstorms is expected to develop to the west
during the day Saturday and move eastward into the area by the
evening and overnight hours. Yet another complex is expected
Sunday night and into Monday. Heavy rainfall and flooding
potential will be the main threats, but at least a limited risk
of severe thunderstorms will also exist. Daily thunderstorm
potential will continue into the early to middle part of next
week, although a slight shift in the pattern toward mid week
should bring increased heat and humidity and some decrease in the
overall thunderstorm chances.
